Stand it up. If the angle is less than 45 degrees the effect will be more pronounced.

I have a D7000 and have already done this, mine is -9 for the 18-105, and also -9 for the 70-300. Is this fine tuning necessary with other Nikons, newer on older? On my previous D5000, I do not believe the fine tuning option is available.
Appreciate your response.

To all who use the D7000 like (GPS Phil)
I have heard that the d7000 has to be ajusted for some lens to get accurate focus , is this necessary ? for all lenses or is it only lower quality Glass?

I spent all evening last evening trying to sort this out , I think I may have it now , but I think its pretty poor that I had to fine tune my nikon 55-200 to minus 7 to get a decent-ish result , I set the lens at 55 mm and fine tuned it to minus 6 and it focused exactly where it should have , but when I zoomed in to 200 mm it was still out , I've had to settle for a happy medium at minus 7 for both ends of the scale , I have yet to test it out hand held

Be carefull with the focus align with a zoom lens - what you align for is the mm setting used NOT the whole range of the lens

The author says you should use Live View, but that’s not essential. Just focus as sharply as you can.

Every lens will act differently on every camera. I had heard folks rave about the Nikon 85mm lens. So I got one. Didn't work worth a darn on my D300 until I fine tuned it for that camera. It worked great on the D2H and later the D700. That being said, it is the only lens I've had trouble with. I now use a D800 and my most used lens is the 24-70 2.8 lens. It is tack sharp.

Set your camera on a tripod, put the autofocus to "SPOT" and lens at widest aperture. Stretch a carpenters tape out on the floor straight out from the tripod. Aim the lens at an even foot mark or something clear like 100 inches, I usually lay a pencil on the floor next to the tape pointing at the mark I used. Autofocus directly on that spot and take a picture. I usually adjust zooms at the longest focal length as that is where they are used most often (200mm on the 70-200). Look at that picture at 200% on your computer and seed what marks on the tape are sharpest. If 98 inches is the sharpest then you are front-focusing a bit. If 103 inches is the sharpest you are back focusing, adjust as necessary and try again until that 100 is the sharpest. If 100 is already sharp the lens is fine and don't mess with it.

This is the method I used and my 55-200 seems to be ok now , my 70-300 is fine without the fine tune , also I found a setting to allow you to see the focus point on the frame taken , this helped me determine whether I was focusing on the correct spot

Is there an easy quick way of checking this?


There's a post here somewhere which includes an easy to use focus test chart. You simply place it at a 45º angle and focus on a dark bar in the center of the chart. Then you open the resulting image and see where the focus actually falls, and then adjust AF Fine Tune to suit - then retest to check the result.

Of course, if you use multiple lenses, some may have diffwerent focus points. So you'd need to remember that. Not sure, but AF Fine Tune may well save settings for given lenses so's you can quickly get back to them.

If you can't find the chart, lemme know and I'll get it to you via PM.

I can't be certain whether this still applies, but back in the film days, if you racked a zoom lens out to full zoom and focused, it would stay in focus when you rack back to the focal length you need.

Almost all fixed aperture zooms still do this. The variable aperture zoom do not.
